The present invention relates to an armature structure in a motor.

In general, the armature embedded in the small motor is constituted by winding the armature core on which a plurality of roughly T-shaped teeth protruding radially from the boss portion are wound, and winding the armature core. As a method, among each of the slits formed between the teeth, a winding group is wound around a predetermined number of slits and wound between the two slits, in which the core axis of the core axis is symmetrical on both sides. The so-called double pliers which carry out and simultaneously carry out this between adjacent slits are widely adopted.

By the way, conventionally, in the case of winding by a double pliers method of double winding, the winding group wound on the slit in the first winding stroke, the winding group wound on the latter winding stroke, in particular, the final winding stroke and the one before it. In the winding group wound in the winding stroke, not only the winding group is not laminated on the outer circumferential side, but also the winding group is wound at a position very close to the opening formed between the locking projections at the tip end of the tee, and is peeled off from the slit. There is a problem of being easy.

Moreover, conventionally, when the winding group wound in the latter winding stroke is wound side by side in the circumferential direction in order to increase the spot ratio in the slit, the winding group wound backward is difficult to enter into the slit, so that the winding stroke of the winding It was a fact that this fall of the production efficiency was caused.

The present invention has been made in view of the above-described circumstances, and has been invented for the purpose of providing an armature structure in a motor capable of eliminating these defects, and the first invention provides a slit of an armature core in which a winding is wound. T-shaped by means of a plurality of tooth bases protruding radially from and the engaging projections protruding from both ends of the tooth base toward both circumferential directions and disposed at the same pitch at predetermined intervals in the circumferential direction. At the same time, the winding group is wound so that the axis of the core axis is symmetrical between the two slits beyond the predetermined number of slits, and are sequentially moved between adjacent slits. Double fold winding of double pliers method for winding a wire, each tee of a bundle of two winding groups wound on each slit In a motor configured to have different winding directions with respect to the base of the switch, in the respective teeth, the base of the teeth, in which the winding group wound in front of the one under the final winding, is held with respect to the center of the circumferential direction of the locking projection, It is characterized in that the preceding winding group is biased toward the slit to be wound, and the length of the circumferential direction of the locking projection to which the following winding group is wound is lengthened.

Moreover, the 2nd invention is the slit by which the preceding winding group is wound with respect to the center of the circumferential direction of the brace | projection part of the chase base part in which the winding group wound by the last winding from the last winding among each tee of the 1st invention is caught. And the length of the circumferential direction of the engaging projection portion in which the winding group following is wound is lengthened.

Moreover, in 3rd invention, the base part which the winding group wound by the latter half is caught among the ties of 1st invention is biased toward the slit by which the preceding winding group of the first half is wound with respect to the center of the circumferential direction of a locking projection part. And it is characterized in that the length of the circumferential direction of the engaging projection portion is wound to the wound group of the latter half.

The fourth invention is characterized in that the number of slits of the armature cores of the first to third inventions is six to twenty.

Thus, the present invention ensures that the winding is deviated from the slit for this configuration, and at the same time, it is possible to remarkably improve the production efficiency.

EXAMPLE

Next, an embodiment of the present invention will be described with reference to the drawings. In FIG. 1, reference numeral 1 denotes a motor. In the case 2 of the motor 1, an armature core 4 and a commutator 5 integrally installed on the core shaft 3, and the commutator 5 ), A brush 6 which elastically slides in contact with the elastic body, and a magnet 7 facing each other at a predetermined distance from the outer circumference of the amateur core 4 are incorporated.

The armature core 4, as shown in Fig. 2, has a base portion 4b of a predetermined width a projecting radially from the boss portion 4a and a predetermined portion at the tip of the base portion 4b. The teeth T1 to T12 are formed in a substantially T-shape by the locking projections 4c which are formed in both directions in the circumferential direction so as to have a width b, and are simultaneously disposed at the same pitch at a predetermined distance c in the circumferential direction. Slits S1 to S12 are formed between the teeth T.

(C) in FIG. 3 is a winding group wound around the armature core 4, and this winding group C crosses four slits S among each of the slits S, and the two slits (two slits ( It is wound about S), and at this time, it is set as one winding stroke to perform on both sides because the axis of the core shaft 3 becomes symmetrical. The winding stroke is sequentially shifted between adjacent slits S, whereby two bundles are wound for each slit S, whereby the bundle group C wound around each slit S is thereby wound. The winding direction with respect to each tooth base part 4b becomes different.

The winding group C is, in an embodiment, a first winding stroke wound between S1 to S8 and S2 to S7, a second winding stroke wound between S2 to S9 and S3 to S8, and between S3 to S10. And a third winding stroke wound between S4-S9, a fourth winding stroke wound between S4-S11 and S5-S10, a fifth winding stroke wound between S5-S12 and S6-S11, S6-S1 And a sixth winding stroke wound between S7 and S12 to be sequentially wound from the inner circumference to the outer circumference.

By the way, among the said teeth T, the tooth base part 4b of the teeth T1, T2, T4-T8, and T10-T12 which the winding group C4-C6 wound around the outer periphery opening of the slit S hangs. ) Is biased toward the slit S to which the winding groups C1 to C3 which are wound beforehand are wound about the center in the circumferential direction of the locking projection 4c.

That is, the length of the circumferential direction d of the engaging projection portion 4c in the slit S, in which the winding groups C4 to C6, which are wound up after being wound up, is lengthened, and at the same time near the opening of the outer circumference of the slit S 2. In the slits S, in which the bundle winding groups C are wound side by side in the circumferential direction, in particular, the slit S6 and S12, the width dimension e on the side of the opening is reduced.

Further, in the above embodiment, the bias amount of the tears T is set to be larger as closer to the final winding stroke, and at the same time, the sixth winding stroke which is the final winding stroke and the winding group C6 in the fifth winding stroke that is one of the preceding winding strokes. And in slits S6 and S12 in which C5 is wound, the slit depth is made shallow so that the spot ratio of the winding group C in the slits S is increased.

In the embodiment of the present invention configured as described above, each of the slits S of the armature core 4 is wound so that the winding group C is sequentially wound from the inner circumference by double overlapping of the double pliers method. The winding groups C4 to C6 wound in the fourth to sixth winding strokes, which are the later winding strokes, are wound near the outer circumferential openings of the slit S.

By the way, the winding base C1 by which the teeth base part 4b of the teeth T1, T2, T4 ~ T8, and T10-T12 which the winding groups C4-C6 are wound is wound before the center of the circumferential direction of the latching part 4c is caught. Since C3 is biased toward the slit S, the winding groups C4 to C6 form a long circumferential length d of the locking projection 4c in the slit S to which the winding group C4 to C6 is wound. C6 is securely caught by the long formed protrusion 4c, and there is no problem such as peeling off the slit S.

In addition, by biasing the tee base 4b of the predetermined tee T, the width dimension e of the side of the opening in the slits S6 and S12 is formed wide, so that the outer circumference of the slits S6 and S12 is wide. When winding two bundles of winding groups C5 and C6 near the opening side by side in the circumferential direction, it is possible to easily wind the winding group C6 to be wound backward into the slit S, and as a result, the winding stroke of the winding group C It is possible to improve the productivity of the work by improving the productivity.

Moreover, in the said Example, since the slit depth of the slit S6 and S12 which winding group C6 and C5 winds is set shallow, and the slit depth of other slit S is set deep, the winding group in slit S The area ratio of (C) can be raised, and the motor performance can also be improved.

In addition, since the width a is secured in the same way as the other tooth bases 4b, the reduced tooth bases 4b can prevent deterioration of motor performance due to unbalance of data. Can be.

In addition, the present invention is not limited to the above embodiment, and for example, the armature core 4 of the 8-slit type or the 16-slit type, as in the second and third embodiments shown in FIGS. 4 to 7, for example. It can also be implemented. In other words, the present invention is suitable for the slit number of the armature core 4 of about 6 to 20, and the tee T, which is biased toward the tee base 4b, is the winding group C in the latter cold stroke. It is desirable to wind up this.

As mentioned above, since the present invention is configured as described above, the winding group is wound in a double overlapping form by a double pliers method on each slit of the armature core, and at least of the final teeth of each slit forming the slit. In the case where the winding group wound by the winding stroke and the winding stroke before it is caught, the base portion of the teeth is biased toward the slit where the winding group wound beforehand is wound about the center of the circumferential direction of the locking projection. The wound wound by the trailing edge is formed so that at least the final winding stroke and the winding length of the winding stroke in front of one of the winding protrusions of the winding group of the winding group are formed long, so that at least the final winding stroke and the winding stroke before the one thereof are formed. The winding group wound at is securely caught by a long formed protrusion.

That is, the conventional problem that the winding group is not laminated on the outer circumferential side and the winding group wound at a position very close to the outer circumferential opening is peeled off from the slit can be reliably prevented.

In addition, in the case where the base portion of the teeth is biased as described above, the width of the slit in which the winding group is wound is increased at least in the final winding stroke and the winding stroke before the one thereof, and thus the winding group is increased to increase the spot ratio at the slit. In the wound side by side in the circumferential direction, it is possible to wind the winding group to be wound in the slit very easily, thereby significantly improving the production efficiency by facilitating the winding stroke.
